This tutorial presents an introduction to power scaling concepts for high-order harmonic
generation (HHG) and attosecond pulse production. We present an overview of state-of-the …

The pulse duration at the output of femtosecond lasers is usually close to the Fourier limit,
and can be shortened by increasing the spectral width. To this end, use is made of self …

In this work, we present a nonlinear spectral broadening and compression scheme based
on self-phase modulation in bulk media inside a Herriott-type multipass cell. With this …

This article offers an extensive survey of results obtained using hybrid photonic-crystal fibers
(PCFs) which constitute one of the most active research fields in contemporary fiber optics …

Sources of short wavelength radiation with femtosecond to attosecond pulse durations, such
as synchrotrons or free electron lasers, have already made possible numerous, and will …

We present a straightforward route for extreme pulse compression, which relies on
moderately driving self-phase modulation (SPM) over an extended propagation distance …

Although ultraviolet (UV) light is important in many areas of science and technology, there
are very few if any lasers capable of delivering wavelength-tunable ultrashort UV pulses at …

We have recently demonstrated a simple power scaling procedure for Kerr-lens mode-
locked thin-disk oscillators. Here we report on the extension of this scheme to a broadband …
